linux-next: build failure after merge of the final tree (drm tree related)

linux-next: build failure after merge of the final tree (drm tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1583 bytes --]

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_buf_destroy':
drivers/gpu/drm/drm_gem_cma_helper.c:38:2: error: implicit declaration of function 'dma_free_writecombine' [-Werror=implicit-function-declaration]
drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_create':
drivers/gpu/drm/drm_gem_cma_helper.c:61:2: error: implicit declaration of function 'dma_alloc_writecombine' [-Werror=implicit-function-declaration]

Probably caused by commit 16ea975eac67 ("drm/tilcdc: add TI LCD
Controller DRM driver (v4)") which forced CONFIG_DRM_GEM_CMA_HELPER to
'y'.  dma_alloc/free_writecombine are only defined on ARM.

I added this patch for today.

[Rob Clark]

Hmm, maybe DRM_GEM_CMA_HELPER should depend on ARM (or !PPC)?  Or
maybe there is an alternative fxn to use on other archs?

In truth, it is fine to make TILCDC depend on ARM, as it wouldn't be
used on any other platform (today.. until TI comes up with some crazy
chip w/ some TI DSP plus display controller), although that doesn't
quite feel like the right fix.  It would be nice to make the CMA
helpers do the right thing on other archs somehow.

BR,

The patch looks fine.

linux-next: build failure after merge of the final tree (drm tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 2535 bytes --]

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/radeon/ci_dpm.c: In function 'ci_request_link_speed_change_before_state_change':
drivers/gpu/drm/radeon/ci_dpm.c:4212:4: error: implicit declaration of function 'radeon_acpi_pcie_performance_request' [-Werror=implicit-function-declaration]
    if (radeon_acpi_pcie_performance_request(rdev, PCIE_PERF_REQ_PECI_GEN3, false) == 0)
    ^

Caused by commit cc8dbbb4f62a ("drm/radeon: add dpm support for CI dGPUs
(v2)").  These calls need protecting with CONFIG_ACPI (like is done in
cypress_dpm.c, I guess).

I tried reverting commit 9c725e5bcdae ("Merge branch 'drm-next-3.12' of
git://people.freedesktop.org/~agd5f/linux into drm-next") but that failed
because that branch is based on v3.11-rc7 (!) which is later than the
base of the drm tree (v3.11-rc3).  :-(

I added this fix up patch for today (it may be wrong, butfixes the build
failure).

Not a biggie, but I noticed that when you added this patch to your tree
you lost the authorship ...

linux-next: build failure after merge of the final tree (drm tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1712 bytes --]

Hi Dave,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/radeon/radeon_fb.c: In function 'radeonfb_create_pinned_object':
drivers/gpu/drm/radeon/radeon_fb.c:144:18: error: 'struct drm_mode_fb_cmd2' has no member named 'bpp'

Caused by commit 308e5bcbdb10 ("drm: add an fb creation ioctl that takes
a pixel format v5").

I applied this (maybe incorrect) patch for today:

Subject: [PATCH] drm: fix up for BIG ENDIAN breakage

Commit 308e5bcbdb10 ("drm: add an fb creation ioctl that takes a pixel
format v5") missed one spot needing to be fixed up in the __BIG_ENDIAN
case.

Fixes build error:

linux-next: build failure after merge of the final tree (drm tree related)

[Stephen Rothwell]

Hi Dave,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/radeon/radeon_device.c: In function 'radeon_device_init':
drivers/gpu/drm/radeon/radeon_device.c:783: error: too many arguments to function 'vga_switcheroo_register_client'

The i386 defconfig build also failed like this:

drivers/gpu/drm/i915/i915_dma.c:1239: error: too many arguments to function 'vga_switcheroo_register_client'

("vga_switcheroo: add reprobe hook for fbcon to recheck connected
outputs") which forgot to update the prototype of
vga_switcheroo_register_client() for the non CONFIG_VGA_SWITCHEROO case.

I applied the following patch for today.
